| 摘 要： | 调查了浙江金华市郊非农田生境43个样地中的58种杂草的重要值，测定了样地土壤pH值、土壤含水量、土壤溶液电导率以及土壤中的Cu、Cd、Cr,Zn,Mn,Pb含量。应用典范对应分析（canonical correspondence analysis,CCA)对58种杂草与9个土壤因子间关系的研究结果表明，对58种杂草分布影响较大的环境因素分别为土壤含水量及土壤中Cd,Cr,Cu和Zn的含量；根据杂草与土壤因子在排序图上的位置关系，指出了具有潜在的耐Cd,Cu,Pb,Cr和Zn等重金属污染的杂草种类。

| Abstract: | The important values of 58 early spring weeds in 43 sites in non field habitats in Jinhua suburb were surveyed.The data including soil pH,soil electric conductivity,soil water content,the contents of soil,Pb,Mn,Zn,Cd,Cu,Cr in the 43 sites were also collected.The relationship of 58 weed species with the 9 soil variables was revealed in two dimension ordination plot using Detrended canonical correspondence analysis(CCA).The results showed that the environmental variables ranked as water,Cd,Cr,Cu and Zn contents of soil according to their importance to the distribution of the 58 weed species in the area.The weed species with potential endurance to heavy metal elements were revealed based on their relations with environmental variables in the ordination plot. |
